. DUMPING BODY.

Application filed September 4, 1928.

This invention relates to a dumpingbody and particularly to a dumpingbody in which a mechanismis provided for causing the body to dump. Ithas for one object to provide in connection with such a body a dumpingmechanism which is non-reversing,that is to say, a dumping mechanism inwhich the actuating parts accomplish both the raising and lowering. ofthe body by moving in the same direction. Another object is to providein connection with a power dumping body a moving contact between thebody and its support. An other object is to provide in connection with apower dumping body means for moving the body to the rear as it is dumpeda distance greater than that due to the tipping of the body alone.Another ob 'ject is to provide in connection with a power tipping bodygreater movement to the rear than that which would take place if thebody were tilted-about a fixed pivot. Another object is to provide inconnection with a dumping mechanism of the type herein an auto maticthrow-out whereby the mechanism is automatically stopped when the bodyhas reached its full dumping position. A further object is to provide anautomatic throw-out whereby the body is stopped when it has reached thefull loading or undumped position. Other objects will appear from timeto time in the course of the specification and claims.

The invention is illustrated more or less dia grammatically in theaccompanying draw- .iLg's, wherein Figure 1 is a side elevation withparts in section andparts broken away showing the body in the undumpedposition;

Figure 2 is a similar view showing thebody in the dumped position;

Figure 3 is a plan view of the vehicle frame, the bodv supporting frameand the dumping mechanism with the body removed;

Figure a is a transverse vertical cross section taken on line 1-4: ofFigure 3;

Figure 5 is a detailed, longitudinal, vertical cross section on anenlarged scale, taken on l ne 5-5 of Figure 3 showing the automaticthrow-out mechanism.

Like parts are designated by like characters throughout thespecification and drawings.

off. A is a pedal controlling the power takeoff. A closure is providedin connection with the take-off, but its details form no part of thepresent invention and therefore it is not llustrated. For the purpose ofthe invention it is sufficient that it is a power take-off and means areprovided for connecting and disconnectingit from thebody dumpingmechanism. A? is avehicle spring, of which there are normally two forsuporting the rear axle A which carries wheels A. The details of thevehicle itself are not important in the present invention, which isapplicable to any vehicle carrying power for dumping. A in dicates thesteering column and A the steering wheel. A is an operators seat; A isthe engine hood. A is a cross member at the rear of the vehicle frame A.

A sub-frame is mounted on the vehicle frame and is made up of the sidemembers B which are preferably in the form of tracks and a forward crossmember B At its rear the sub-frame is supported upon the vehicle frameby means of supporting sections B These may be in the form of a pair ofmembers or they might be a single member extending fully across thevehicle frame. At its forward end the sub-frame is supported on membersB These members also may be a pair of members or they may be a singlemember extending fully across the vehicle. Their purpose is to raise thesub-frame slightly and to form an attachment for it.

C is a cross member joined to the side members B, B of the sub-frame. Itis preferably of angular cross section and is fastened to members C Cwhich are themselves also joined to the side members B, B. C is alongitudinal bracing member joined to the member G at its rear end andat its forward end joined to the cross member B C is an angular bracingmember joined at one end to one of the members 0 and preferably alsoabutting against the cross member C. At its which includes adjacent itsforward end a cross member D This member may be made in channel sectionas shown. D is a hinged tail gate normally held closed by a latch Dwhich may be opened by a connecting rod D The details of this latch andlatch opening mechanism are not shown as they form no particular part ofthe present invention. D, D are rockers supported on the under side ofthe body I) and. preferably joined to' the frame D ,D D are bracingmembers positioned within the rockers D and adapted to strengthen themand to assist in supporting the body.

E is a latch member pivotally supported at. E on the cross member H Itis provided with the hook port-ion E which has an inclined face At itsopposite end it has a lateral projection i which preferably carriesaroller contact member E. It is embraced by a U-shaped nicaiber E whichpasses through an extension on the forward web ofthe cross member B Atits outer ends the U-member E is threaded and carries nuts E, E whichconfine springs E E These springs at one end bear against the web of thecross member B and at the other against the nuts E thereby drawing theU-member E against the latch member and tending to hold it in thelocking position and against n abut ment E which is mounted on the crossmember B lVhen the body is in the loading or undumped position, thecross member I) of the body frame D rests upon the abutment E and thelow r flange of the member D is engaged by the hook E The U-menibcr Eand the springs E hold the hook against displacement and thus preventaccidental tipping of the body due to accidental unlatching of itsforward end.

F is a universal joint through which a connection is made from the powertake-oft A F is a shaft upon the universal joint F. F is a seconduniversal joint. F is a reduction gear of any suitable type. It is notillustrated in detail as the invention is not limited to any particularform of reduction gear. A shaft projects from the reduction gear andcarries a pinion F F is a second shaft pivoted in the base member C andat its outer end in the member F. F is a gear carried by the shaft F. Fis a crank arm fixed on the shaft F adapted to rotate it. At its otherend it is pivotally connected at F with a connecting rod F which isitself pivotally connected to a portion of the sub-frame D as at F G isa cam member fixed on the shaft F". It is provided with a cam part G anda second cam part G These parts are substantially 180 apart and in theform of the invention shown herewith, they are off-set so that they liein different, although parallel vertical planes from each other. G is ashaft fixed at one end in the longitudinal member 0 and at the other inthe member F. It carries pivoted upon it cam arm G which has a nose Gadapted to be contacted by the cam member G it has a lower extension Gwhich is pivotally joined to a connecting rod G which is fastened to thepedal A which operates the clutchmechanism to throw in and throw out thepower take-oil. G is a second cam arm carrying a nose G", a lowerproject-ion G and a connecting rod G. This rod is provided with anoff-set portion G which embraces the connecting rod G G is a set screw.\Vhen the set screw is fastened, the connecting rod G and the connectingrod G move together. It may be run fastened so that the connecting rod Gwill move without causing movement of the connecting rod G. The cam noseG" is adapte: to be contacted by the cam member G The cam member G willcontact the nose G of the am arm G and through it and through theconnecting rod G will operate the power take-off clutch to cut off thepower just as the body has been brought back to the undumped positionshown in Figure 1. Thus a careless operator cannot runthe hoistingmechanism so as to lower the body and unlatch the mechanism. It has beenfound that sometimes this would happen and the body would be leftunlatched, though. practically in the horizontal position. When the bodyis thereafter driven over rough roads accidental tipping might occur.This automatic throw-out thus prevents movement of the body and preventsits being accident-ally .unlatched. Sometimes it is desirable to throwout the hoisting mechanism when the body has reached the full dumpingposition. \Vhen this is the case the set screw G is tightened and thenwhen the bodyreaches the full dumping position the cam member G willcontact the nose G of the cam lever G and through the connecting rod Gwhich is now attached to the connecting rod G it will operate the clutchto cut out the power. There is thus provided a selec tive means wherebythe power may be cut out automatically when the body moves to the fullhorizontal position and is latched and also there is provided aselective means whereby the hoisting mechanism may be automaticallythrown out when the body has reached the full dumping position.

It will be seen by reference to the drawings and the foregoingdescriptimi thereof that the truck to which the present invention isapplied is one of that type in which gravity is utilized to a largeextent in causing the tilting body to dump the load and in the restoration of the body, after the load has been dumped, to normal orhorizontal positionthese functions being secured by the employment ofrockers l'catcd between the tilting body and the supporting chassis orvehicle frame. in apparatus of this character the body has a movementasa whole to the rear when it is elevated for dumping, and back toward thefront as it-is restored to normal position. the body and the vehicleframe are so disposed, in the form of invention illustrated, that thecenter of gravity of the load when The rockers or supports between.

the body is normally tilled is somewhat in ad vance of the verticalplane of the rocker supports on the chassis, with the result that thebody is stably supported upon the vehicle, and the tendency thereof totilt during transit is reduced to a minimum. However, a considerablepart of the load to the rear of the line of support, and this partcounterbalances a con spending portion in advance of" thesupport so thatthe amount of power taken to cause the tilting body to dump the loat isrelatively small. I am thus able to utilize comparatively light.mechanism for control ling the tiltiig' movements of the vehicle body,such as illustrated in the drawing. As has been explained this mechanismis connected with a source of power in such manner that the turningshafts thereof are always driven in the same directions, thus making itunnecessary to employ a reversing mechanism as a part of the gearingthat effects the tilting of the body, and thereby enablinga low-cost, aswell as simple and light mechanism to be successfully used.

A body supported as ill st ated in the drawings-that is upon r 3s--has acom pound movement while being dumped, including a tiltingof the bodyabout its supports the lines of support shifting c onstantly during thetilting operations and at the same time a. bodily movement to the rear.This has necessitated the use of a novel motordriven mechanism tocontrol the tilting of the body in order. that the proper movements maybe imparted to the body, and such mech anism be located within thelimited space available therefor in a practical. dumping truck of thecharacter to which my invention is adapted. It will be seen by referenceto the drawings that the pitman link F, between the crank arm F and thebody of the vehicle. normally extends from the crank in an iunvardlyinclined direction toward the rear so that the thrust of the link toraise the body is in a rearward as well as an upward direction. It willalso be seen that the pivotal connection F between the link F and thebody is located on the far side of the center of the body that is towardthe rear thereof, and preferably close to the vertical plane in cludingthe rocker supports of t is truck body.

Another feature to benoted is that the location of the contact roller ofthe latch E relative to the end of the crank F that operates it issuchthat the latch is operated to re lease the body at themoment thecrank is passing its forward dead center position, with the result thatthe unlatching operation takes place while the link F being moved acrossthe line passing through the centers ofthe pivotal connection F andshaft- F and henceis not operating to tilt the body, this tiltingmovement not commencing until to control the tiltn invention isparticularly applicable, are very commonly operated over rough terrainand are intended to be driven at times at quite high speeds, and theseconditions of use impose the necessity of making the frame of greatstrength to resist the torsions, strains, andv jars to which it issubjected in orcinary uses. The construction of the truck frame orchassis therefore leaves but little free available space beneath thebody in which to mount the power mechanism for tilting the truck, itbeing remembered that provision must be made for the necessary mechanismthat is incident to an automotive vehicle of present day construction.Bearing these *erations in mind, I mount the principal parts of the meclanism for controlling the tilting movements of the body between thevehicle frame or chassis and the body, and in advance of the supportingrockers. As this mechanism is non-reversing the crank F thereof iscaused to make complete revolutions and is relatively short as comparedwith the link or pitman F connected therewith, which. as has beentitted. ext-ends rearwardly and upwardly to its connect-ionat F with.the body.

It is quite conceivable that a body, arranged and supported asillustrated in the drawings eof,n1igl1t be loaded so that either it willautomatically dump and restore itself by gravity alone, or so that thecenter of gravity of the load will be to the rear the line of support onthe chassis or truck body. In such. cases the gearing illustrated,including the link F and the uni-directional motordriven mechanism. willoperate either solely g movements ofthe body or both to control andres-train them. However the body may be loaded, the mechanism shownserves to. control the tilting movements thereof, and this control iseffective without the expenditure of an excessive amount of power and isapplied smoothly, preventing the slamming or excessive arring of partsin operation with incident wear and tear on the apparatus.

It will be obvious that while i have shown an operative device, manychanges may be made in tile size, shape, number, relation anddistribution of parts withoutdeparting mate ially from the spirit of myinvention, an I wish. therefore that my showing be con sidered in alarge measure diagrammatic.

The use and operation of this invention are as follows:

The body is assembled on a vehicle having a power source, in the generalposition shown.

The automatic cut-off which stops the body when it reaches the fullhorizontal position when it has been latched is normally in opertion.After a load has been taken on and the vehicle moved to the point wherethe load to be dumped. the operator, through the clutch pedal of thepower take-off, sets lit) the power take oil in position and the gear Frotates, and. through the crank arm F and the connecting rod F, the bodyis tipped. However, before the body may start its tipping movement itmust be imlatched from the latch The parts are so proportionei'l that aslight rotation ot' the gear F and the crank arm F takes place beforeupward movement oi the body starts. In this first stage of the movementof the crank arm F the outer end of this arm contacts the roller on theextension E of the latch E, depresses it and so moves the latch todisengage it from the body frame. Dumping movement of the body is nowpossible. As this takes place, the body moves not about a fixed pivotbut moves rearwardly upon the rec which support it upon the track. lVhenthe body has reached the proper dumping position it may be stopped thereby the operator or if the automatic throw-out is in operation the bodymay be stopped at the full dumping position automatically. hen the bodyhas been dumped the operator again operates the clutch controlling thepower take-oil mechanism and so sets in operation the hoisting movement.Rotation of the gear F continues in the same direction and the body nowmoved to the horizontal position. As it moves to the toll undumpedposition the member D contacts the tace E of the latch E and springs itrearwardly against the resistance of the springs E The latch rides overthe mem ber D and engages it. Just when this is com plet d the automaticpower shut off operates and the hoisting mecnanism is stopped.
